The inner arc sides 38 of the two arc-shaped anode plates are on the same arc with the corresponding cathode wire 4 as the center, so that a uniform and stable main corona area can be formed between the cathode wire 4 and the anode plate body 37, and the condition that the power output is reduced due to the flash in the operation process of the traditional dust remover is avoided; the distance between the anode plate bodies 37 is reduced in the process that the smoke dust which is not trapped after the main corona area is charged enters the secondary corona area, and the smoke dust is trapped by the anode plate.
The inner arc sides 38 of two adjacent arc-shaped anode plates are opposite, the outer arc sides 39 of two adjacent arc-shaped anode plates are opposite, and a cathode wire 4 is arranged between the inner arc sides 38 of the two opposite arc-shaped anode plates and is called as a main corona area; the area of the outer arc side 39 of the two opposite arc-shaped anode plates is a secondary corona area, the cathode wires 4 in the two adjacent flue gas channels 8 are alternately arranged, and the anode plates 3 and the cathode wires 4 jointly form a dust collection area.

The porous area 33 on the side part of the anode plate capable of flowing is arranged in the upstream and downstream areas (namely the arc area with the radian of alpha minus the arc area with the radian of beta in figure 5) of each anode plate body 37 along the flow direction of the smoke, so that the possibility of overlarge local flow velocity possibly generated when the charged smoke dust on the upstream passes through the corona once area is avoided; meanwhile, the smoke dust in the charged dust-containing smoke partially passing through the porous area 33 on the side part of the anode plate can be trapped by the anode plate body 37, and the partially escaped smoke dust enters the main corona area on the other side of the anode plate body 37 and is further charged to and fro until the smoke dust is trapped (as shown in figures 5 and 7).
